This is the one for 3000 miles, is this the weaker version people were saying is not too usefull? or is this the "good" concentrated one that should be used sparingly?

Another thing, if you're looking to get this at your local Advanced Auto and don't feel like purchasing online and printing out a piece of paper for in store pickup they will NOT match the price of a single bottle there for some stupid reason. In store however they're doing a buy one get one free on it so you gotta get 2 to get 1 at that price. When I was in store though I realized it said 3k miles on it and I wanted to double check back here to make sure it's the right one that's worthwhile to get, plus I only want one.

I hope you disclosed that you were trading in a bum vehicle. It is not like you stuck a dealership with it. They don't keep it, they sell them, most of the time without knowing that there may be an issue with the vehicle.

So, now the next owner is stuck with it, when it could have been fixed perfectly by you pursuing the gas station owner.

That is exactly why I always tell people not to buy used cars. People usually don't sell perfectly running vehicles. they keep them, until there is a problem that they don't want to fix and just want to stick someone else with a bill.

Lol like dealerships actually care about anything else besides making a buck? Going to a dealership and not having your car properly checked out is like going to prison and just bending over all day.

That's what mine says as well, but also says it can be used every 3000 miles. An older bottle of the concentrate says not to use it more than once every 20,000 miles, suggesting the concentrate is now less concentrated.

How old is the bottle that says 20,000 miles? I haven't seen those in over 10 years. They used to sell those retail, but stopped, probably because of the concerns you raised. I believe the only way you can get them now is if you have a repair shop. And it may only be used if you have a "fuel injector" machine that feeds it into the injectors directly, not through the fuel pump.

All these "magical" fuel injector cleaners are a blend of xylene, toluene, and probably hexane or pentane, which are really strong solvents and will dissolve most polymeric plastics, which are now commonly used in the fuel supply systems.

The older ones may have had tetrahydrofuran which will "digest" pretty much any polymeric plastics.

I am aware that this Thread is rather old but I still want to make a reply.
